beetle - Rhyncolus oregonensis

beetle - Rhyncolus oregonensis
Oakland, Alameda County, California, USA
May 5, 2006
Size: 4.5mm
Found under bark of a dead Monterey Pine tree in the Oakland hills.

Rhyncolus oregonensis Horn
Charles O'Brien det.

Moved from Rhyncolus.

Curculionidae: Cossoninae: Rhyncolus sp
I think it is a Rhyncolus sp., found under bark of conifers and other dead trees.

much better choice.
vaguely reminds me of

one of the other weevils - Scolytinae

A good reason
as to why the Scolytids and Curculionids were combined - the cossonine weevils and some of the scolytid genera begin to blend together. Scolytids typically have a very distinct antennal club, while the cossonines have much less distinct antennal clubs.

Bark weevil?
I'm pretty sure this is a bark weevil. Genus Pissodes???

Dendroctonus seems more likely to me
Dendroctonus or similar, as opposed to Pissodes
